I lived in a town with 50k back in the 90s. I don't remember there ever being a bus service except for the school buses.
The town was pretty massive though. Half the town was on a plateau as well so you had to walk up a pretty huge hill to get to half of it.
There was quite a few taxi's driving people around.
Maybe there was a bus that I never used and can't remember. As a kid I rode everywhere. That hill was a son of a bitch though.
No they wouldn't. The system is terrible. Lidar would help with the shitty phantom breaking but that's all.
